To all whom it may concerwl V Be it known that I, WALTER ALLWARD,

citizen of the Dominion of Canada, residing' at Vancouver, in-the Province of'BritiSh Columbla, Canada, have lnvented certain new and useful Improvements in Drill Holding Magazines,of which the following stand, from which they -can be selected as is a specification. e This invention relates to a magazine for holding small dental vdrills or the like articles, and for presenting one of each kind in a-readily accessible manner for'"use{ iDentists at present usually retain their supply of small drills, which are ready for use, in-

vertically disposed aperturesin a revolvable I required, but as the stand is designed to hold 3 posures. V l w 1 In the device which is the SLlbJQCt of this; application, a considerable number of drills a number ofeach'kindof drill, and all are exposed to View, difficulty is experienced in selectingthe drill wanted from so many ex.

or' each kindare retained, one above the other, in separate recepta'cleal'from which the lower one only of each kind, isprojected through: an aperture for inspection'and withdrawal. i

Each row of delivery apertures is also. provided with a 'retainin o clip for number bearing tickets, that the cIrills in the magazine may be identified by number, if not by inspection; 7

The invention is particularly described-in the following specification, reference being made "to the drawings'b-y which it'is ac companied, in which i Fig. l'is a perspective view of the maga z1ne,a portion of the casing being removed.

. Fig. '2 is a 22, and p 7 I 3 is a perspective viewof thed'rill projector. 77 ,7 1 V The magazine comprises a substantially rectangular box likejcasinga ofthin sheet vertical sectionon the plane metal, having Qa cover [3 closing the open top, which cover is preferably hinged to the back edge of the'casing. e e i In the middle of the front wall of this vcasing, r near the bottom, is an aperture to receive the drill projecting'fplunger 12.

Abovethis plunger 12, is a row of small apertures 4:, adapted toj freelypass "a drill, and above that is another row of similar apertures 5, spaced between those 4.-

The casing is providedlwith small feet 6,

facetodea've'a space between its sbacki'and the back of the casing to allow for the movement of the drillprojectorS l-of'the casingand extending from the top of the block. to thelevel of these apertures.

- "Spaced between the slots' '8, similar slots 9 adapted to hold the shorter drills, extend from the top of the'block higher row of apertures 5 n this block 7 a number 01: drill holding slots -8 are cut to register with the apertures 7o t -o the level of the When the block 7 is secu ed Wifhinit'he casing [2,the slots Sand 9 fornise'parate receptacles for anumber of; drills of each kind, and the bottom drill of each recepe tacle may be projected throughfthefapertures'c and 5 of the casing 2.

The means by which theibottom dam v each receptacle 8 and, 9is projected through the apertures and 5}respecti'vely, comprises a bar l O adapted to slidably-fit, a

transverse groovee tendi-ng alongltheback of- 'the block? at thelevel of-theslots 8 andnore mally projecting into the back end of the slots" The back edge of thisgb ar L10 is up- 1 wardly turnedand in the backwardly turned 7 portion, is secured'a series ofpinsll fitting holes drilled through the block from the back into theibottom-ofeach slot 9; As in thecase of thebar- 10, these-pins '11- normally p'roject'a short distance into theslots9 to I projectthe "front end ofeach bottom drill through its aperture 5 of the casing.

The. plunger 12 by whichmovement of the projector is effected slidably 'fits tureofthe casing, and 'a corresponding ape'rj ture-in the block 'diameter to receive aspring 1 3 coiled'ion it the apera '7'with jwhichitregisters';

Withintheblockftheplunger is reduced in j r between the shoulder'o'fthe reduction, and a V retaining washer plate '14; through which before attachmentofit to the bar l0. g'This spring 13 normally holdsthe bar 10 and itsattached pins at the inner' limitoif its the reducedportion of the plunger passes arecharged respectively with the longer and f shorter drills, each receptacle being reserved for drills ofpne'ikin'd, v Asthe projecting hello e fi e e t i e x n heme attached to. thatbar project into the after end of each slot or receptacle 8 and 9 at the level of the bottom, the bottom drill'in each receptacle'will rest with itsaiter end on the bar or on one of the several pins '11 as the the after end path of movement of the'l'oar 10-andp-insll, and on relieving the pressure on the plunger,

As used, a dril-l'may. be discarded for cleaning and sterilization inreadinessfor another patient, and 01 sliarpsni ng if necessary, and after; treating, such drills are returned to; their respective receptacles.

Qbviously, the bar- 1 0; may: be channel shaped and the back of the block betranse versely groored to receivethe upper edge of; the channel bar inalignment' with a the severalv shorter drill' slots 9, in the same manneras the bar lOizacts in relation to the longer drill slots 8, but when this is done the drills, being short, are liable tohpvass angularly from theirv slots into thetrans verse'groove of the projector when thesarne I is withdrawn. It, isfor this reason that the pins, 11 have'heen adopted as projectorsfor' the short drills. e
